Procedure

(S)-Methyl 6-((4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenamido)-2-(nicotinamido)hexanoate (40 mg, 0.0695 mmol) was taken up in 2 mL of THF along with 80 μL of a 5 M NaOH solution. The resulting reaction mixture was stirred at room temperature for 2 h. It was then acidified to pH 4 with 2 N HCl and then extracted with EtOAc. The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure to afford 31 mg of (S)-6-((4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenamido)-2-(nicotinamido)hexanoic acid. MS calculated for C34H47N3O4: 561.36. found: [M+H]+ 562.
